Abstract
Description
Technical Field
[0001] The utility model relates to the field of medical equipment, in particular to an oxygen absorption mask. Background Art
[0002] An oxygen mask is a device used to provide oxygen for breathing, mainly including medical oxygen masks and civil aviation oxygen masks. Medical oxygen masks are mainly used to treat diseases, such as respiratory medicine, neurology, gastroenterology, oncology, ICU, surgery, obstetrics and gynecology, etc. The principle is that oxygen flows continuously into the air storage bag of the mask through a thin rubber oxygen supply tube and a bayonet joint connected to the automatic connector. The air storage bag first stores air and then expands to accommodate a certain amount of oxygen. Some frail elderly people who are bedridden all year round often need to wear oxygen masks for a long time. When wearing an oxygen mask for a long time, water droplets are easy to form on the inner wall of the oxygen mask. As the water droplets accumulate, they will flow down along the inner wall of the oxygen mask to the patient's face, causing the patient to feel a certain degree of discomfort. Utility Model Content

[0019] A connecting mechanism 4 is provided at the front end of the mask body 1, and the connecting mechanism 4 includes a connecting base 401, a connecting through hole 402, a connecting cavity 403, a connecting pipe mouth 404 and a filter core 405. The connecting base 401 is connected to the mask body 1, and a connecting through hole 402 is opened at the edge of the connecting base 401. A connecting cavity 403 is fixedly installed on the connecting base 401, and a connecting pipe mouth 404 is connected to the connecting cavity 403. A filter core 405 is provided in the connecting pipe mouth 404. The entire mechanism can be connected to the mask body 1 through the connecting base 401, and the oxygen tube can be connected to the mask body 1 through the connecting pipe mouth 404, and the filter core 405 can connect to oxygen for filtering.
[0020] A guide mechanism 5 is provided at the inner edge of the mask body 1, and the guide mechanism 5 includes a limiting protrusion 501, a guide groove 502, a docking port 503, an elbow 504 and a guide pipe 505. The guide groove 502 is installed on the inner wall of the mask body 1, and the limiting protrusion 501 is fixedly installed on the outer side of the guide groove 502. The guide groove 502 is provided with a docking port 503, and the docking port 503 is connected to the elbow 504, and the elbow 504 is connected to the guide pipe 505.
